The Analyses Of The Main Factors Influencing The Accuracy Of Fire Of Aerial Rockets

The development of aerial rockets is always baffled by the accuracy of fire. It must be set out to do from two sides. One is helicopters, and the other is rocket projectiles. All kinds of factors influencing the accuracy of fire of the aerial rocket projectiles must be analyzed roundly in order to increase the accuracy of fire of aerial rockets. According to the practice of the aerial rocket engineering development, this thesis has analyzed the main factors influencing the accuracy of fire of aerial rockets. The research is based on the theory of dispersion of conventional rockets and exterior ballistic theory. The research works of the thesis as follows:Firstly, the thesis has enumerated all kinds of factors which has happened or would be likely to happen during the scientific research. The thesis has analyzed emphatically the initial disturbance, helicopter rotor wing downwash flow, helicopter flight state influencing the accuracy of fire aiming at the characteristic of aerial rockets. The thesis hasn't developed the initial disturbance which belongs to the typical category of conventional rockets in detail. The thesis has analyzed and calculated in detail the influence cause of helicopter rotor wing downwash flow and flight state. Finally, the thesis has accomplished the simulation computation and comprehensive analysis for the analysis method and conclusion combining test results of special scientific test.To sum up, this thesis has accomplished plenty of analysis and calculation for the main factors influencing the accuracy of fire. The analysis and calculation were based on summarizing scientific research test. At the same time, plenty of accumulated test datum were applied in this thesis. This thesis has studied actively many factors influencing the aerial rocket accuracy of fire and get a lot of beneficial conclusions.
